Answer:
Homeostasis
Explanation:
Homeostasis is the maintenance of a steady-state/condition in the body to ensure the optimal workings of the cells. Blood sugar level is one of the variables in the body that also has to be maintained through positive and negative feedback loops to maintain the desired level. Insulin is the hormone used for negative feedback (to reduce the blood sugar level when it goes higher than the normal level) and Glucagon is the hormone for positive feedback (to raise the blood sugar level when it goes below the normal levels).
Ectopic focus or ectopic pacemaker happens when an excitable group of cells outside the normal sinoatrial node causes premature heartbeat. Sinoatrial node (SA node) is the pacemaker of the heart. Most people experience ectopic focus but persistent occurrence may need the client/patient to visit the doctor. If a client or patient complains of ectopic focus, it is better to consider his/her activity before visiting the clinic. Ask, for example if the client/patient had a vigorous exercise because it might be causing the irregular heartbeat, how often is he/she experiences such irregularity in his/her heartbeat (acute ectopic foci is usually non-life threatening, however, chronic type requires medical help), his/her lifestyle (he/she might be using illegal drugs, smokes and/or drinks alcohol,had too much coffee etc). Again, history taking is very vital.
It’s the 3rd one! The O + O!!
